It complicates Obama's relationship with Israel

These are troubled times for President Barack Obama.

He's a lame duck president. The latest CNN/ORC poll has his approval rating at 41% -- the lowest of his presidency. And the Affordable Care Act, his signature legislation, has been hobbled by the botched and much maligned rollout of the signup website.

"Today, diplomacy opened up a new path toward a world that is more secure," Obama said in a televised address from the East Room of the White House, after the deal was announced. "A future in which we can verify that Iran's nuclear program is peaceful and that it cannot build a nuclear weapon."

But will the agreement be enough to help distract the public from the Obamacare rollout debacle and potentially improve his image?

The deal complicates Obama's relationship with Israel, a key ally in the region. Israeli Prime Minister Benjamin Netanyahu strongly oppose any deal, and the Israeli government had strong words Sunday.

"The current deal ... is more likely to bring Iran closer to having a bomb," Intelligence Minister Yuval Steinitz, a close Netanyahu associate said. "Israel cannot participate in the international celebration, which is based on Iranian deception and the world self-delusion."

The deal says that the U.S. will provide $6 to $7 billion in sanction relief in exchange. And Obama can do so by executive order -- bypassing Congress altogether.

Reactions poured in late Saturday night, with Republicans slamming the administration for appeasing the Iranian regime.

"This deal appears to provide the world's leading state sponsor of terrorism with billions of dollars in exchange for cosmetic concessions that neither fully freeze nor significantly roll back its nuclear infrastructure," said Sen. Mark Kirk, R-Illinois.

U.S.-Iranian relations have been thawing for months now, since the election of Hassan Rouhani as Iran's seventh president in June. A senior administration official confirmed Saturday that since the election, U.S. and Iranian officials have been holding private, previously secret discussions to generate ideas for the wider nuclear negotiations.

The détente climaxed in a telephone conversation between Obama and Rouhani this fall during the United Nations General Assembly -- the highest contact between leaders of the two countries since the Islamic revolution that led to the Iranian hostage crisis in 1979.

"While today's announcement is just a first step, it achieves a great deal," Obama said. "For the first time in nearly a decade, we have halted the progress of the Iranian nuclear program and key parts of the program will be rolled back,"

Ultimately, however, the outcome -- and part of Obama's legacy -- hinges on what happens next: Negotiations will continue over the next six months to reach a comprehensive solution to the Iran's nuclear program.

"The success of interim deals will be measured in months and years, not in minutes," said Karim Sadjadpour, a leading researcher on Iran for the Carnegie Endowment for International Peace.
